支持五级混编、稳定种子、容量预检、固定考点、逐科考场/座位及四种准考证号规则。

正式编排会事务性替换整场计划、准考证、座位和审计记录。
支持三级管理员范围读取、批量 HTML 准考证、准考证信息 Excel，以及校级考点桌贴、门贴和签名单。
核心实现见 [AdminArrangementPlanner.cs (line 7)](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Administration/AdminArrangementPlanner.cs:7)、[AdminArrangementService.cs (line 11)](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Administration/AdminArrangementService.cs:11) 和 [AdminArrangementExporter.cs (line 5)](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Administration/AdminArrangementExporter.cs:5)。
新增开关 ADMIN_NATIVE_ARRANGEMENTS_ENABLED=true，说明已更新到 [MIGRATION.md (line 57)](C:/Users/BI/Documents/EIS-dotnet/MIGRATION.md:57)。
Excel 由 .NET 直接生成，使用 ClosedXML 0.105.0；该库支持服务端生成 Excel 2007+ 工作簿。ClosedXML NuGet 页面
